No dog leaves GRROW's care that is not A-1 OK. GRROW even provides help for expensive surgery for displastic dogs and treatment for heartworm. If the dog is deemed unadoptable, a "foster mom" provides a loving and kind home for the dog's final days. Nobody makes any money off of this work. Most of the vet care is donated, as is all of the fostering. Added fees would really strap this organization and result in fewer adoptions.
My precious Golden was found as a stray, and he has become the center of my home and my office. He is the office dog and sleeps in the President's office because that is where the carpet is. The President (my husband) conducts his work from an auxiliary office so that Max can relax in the luxury he deserves as the company mascot.
Max was a wild young thing when I first got him four years ago at about 8 months, but GRROW's rules required that I take him for obedience training. He is a perfect gentleman now. And GRROW's rules also decree that if I ever find that I can no longer keep him, he must be relinquished back to GRROW. I cannot pass him on to a third party that they do not know -- not even to my own children.
Not only are most of the dogs given up for adoption to rescue groups large dogs, as doc mentioned, 3/4 of them are males. They are just like rowdy teenagers, but with the right training quickly develop into responsible young men.
Max was deemed unsuitable for a family with children (he knocked my husband to the ground with his exuberance the day we first met him, but we still fell in love with him), and you can see by this picture with one of my grandchildren that he has come a long way:
And he no longer wears a "prong" training collar, either -- a soft collar will do just fine. He does consider leashes beneath him because he knows how to walk all by himself, thank you very much, although he will tolerate them when necessary. He is truly a Golden Angel.
